To all whom 'it 'may concern:

Be ity ,known that l, Les D. HAMACHER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Loose-Leaf Books, of which the following is a specification.

AMy inventionrelates to in'iprovements in loose-leaf books, and my object is to provide a simple and inexpensive device of this char- In carrying out the invention I employ a frame consisting of a concaved channel-bar 1, provided with longitudinal marginal flanges 2, forming longitudinal grooves 3.

4 designates a metallic binding-strip having slots 5 to receive downturned prongs 6 struck from the channel-bar.

7 designates a strip of binding material interposed between the channel-bar 1 and the binding-strip 4, it being reliably secured between the same by the prongs 6, which extend through the slots 5 and are upset against the underside of the binding-strip, as shown in Fig. 2.

8 designates the cover to which the binding-strip is glued, or otherwise secured;

9 designates a pair of hook-carrying meinbers, rockingly-mounted in the channel-bar and reinforced by means of ribs l0, to resist torsional strains. Members 9 are provided vat their abutting adjacent. sides with fingers 11, the fingers on one membe'r underlying the companion member to compel said members to operate in unison and also to limit the opening movement of a plurality of hooks 12, carried thereby. The closing movement ofthe hooks is checked by their contacting with each other, and in order to hold each pair of hooks inA radial alinement, one set is provided with V-shaped tongues 13, which enter V-shaped groovesl14 in the opposing hooks. Each hook-is provided with a shank spective hook-carrying member, where it is soldered or otherwise reliably secured.

1U d ignates a pair of resilient members in the orm of corrugated springs, which are arranged in grooves 3, and abut against the adjacent edges of the hook-carrying members '9, in order to reliably hold the same in either of the positions shown in Fig. 2.

1T designates a pair of caps which may be formed integral with the channel-bar l, or made separate therefrom as shown in Fig. 3, in which latter case it is slipped over the ends of said channel-bar and reliably secured thereto, these caps having nothing to do with the operation of the device, but are merely added to` give an ornamental or finished appearance thereto.

.although I have shown the preferred form of my device, l, ofcourse, reserve the right to make such changes as properly fall within the spirit and scope f the invention.

Having thus described my invention, what l claim is 1. A device of the character described consisting of a frame, hook-carrying members roekingly -mounted therein, and resilient members interposed between said frame and the hook-carrying members.

2. A. device of the character described consisting of a frame,hook-carrying members rockingly-mounted therein, means carried by the hook -carrying members to limit the opening movement of the hooks, and resilient members interposed between said frame and the hook-carrying members.

3. A device ofthe character described consistinp; of a frame, hook-carrying members roekii fly-mounted therein, and corrugated resilient members interposed between said frame and the hook-carrying members;

4. A device ofthe character described consisting of a frame provided with marginal flanges forming grooves, resilientl members 'arranged in said grooves, and hook-carrying members roelringly-mounted in said vframe and abutting against said resilient members.

A device of the character described consisting of a channel-bar, hook-carrying members rrockingly-mounted therein, and having their innerl edges abutting against each ither4 and resilient members interposed between the sides of the channel-bar and the outer edges of said hook-carrying members.
